# Installation

Setting up the Polkasafe SDK is a straightforward process. 

Here's a step-by-step guide to installing and using the SDK:

> NOTE: Polkasafe is built on top of the Polkadot.js API, so make sure you have also installed the required packages: @polkadot/api and @polkadot/extension-dapp.

```
// npm
npm install polkasafe bn.js dayjs 
```

#### Creating an Instance

```typescript
import { Polkasafe } from 'polkasafe';
const client = new Polkasafe();
```

> NOTE: Connecting with polkasafe is essential. Before using any functions, use connect function to set the network, address, and injector.

```typescript
/**
 * @param {string} network
 * @param {string} address
 * @param {Injected} injector
 */
// injector: Simplify transaction signing and submission using the injector parameter
client.connect(network, address, injector)
```

Replace network, address, and injector with your specific values. That's it! You have now set up the Polkasafe SDK and you are ready to start using it in your application.
